CLEANTECH VENTURE DAY
PARIS
28 November 2025
The ultimate meeting place for UK and EU innovators, investors, large enterprises and economic development partners to see next generation climate tech solutions and investment opportunities.
On 28 November, Cleantech Venture Day makes its Paris debut, following Amsterdam and London, and further cementing the Climate Tech SuperCluster as Europe’s home for climate innovation.
Taking place at Capgemini’s headquarters, the event brings together startups, investors, corporates, and ecosystem partners to explore the next generation of energy and building infrastructure — the systems Europe urgently needs to become more resilient and independent. From how we generate and manage power to how we design and operate the spaces we live and work in, the focus is on scalable solutions that can accelerate the transition. 12 startups will pitch to an audience that blends venture capital with leading enterprises, showcasing how corporate–startup collaboration can help build the foundations of a more resilient, low-carbon Europe.
The Paris edition kicks off the evening before with a reception on 27 November at the Climate House, held in partnership with London & Partners and J A Kemp. An informal gathering featuring a short panel and networking with delegates from across Europe.

NETWORKING EVENT
Thursday 27 November
Climate House, 39, rue du Caire, 75002 Paris
On the evening before Cleantech Venture Day Paris, join us for an exclusive networking reception at the Climate House. Bringing together around 90–100 delegates from across France and abroad – including innovators, investors, corporates, and ecosystem partners – this pre-event is the perfect opportunity to meet key players ahead of the main event.
The evening will open with a short welcome and a 20-minute panel discussion, “From London to Paris and back – Where can innovation best thrive?”, hosted in collaboration with our partners London & Partners, J A Kemp, and Climate House. The conversation will highlight the complementarity between two of Europe’s most vibrant climate tech ecosystems, setting the stage for cross-border collaboration and new opportunities.
The reception takes place at the Climate House, in the heart of Paris’ Sentier district. Founded by a collective of 80 entrepreneurs, it was created to reinvent the economy in service of the ecological and social transition. More than just a venue, Climate House is a community of entrepreneurs, investors, researchers, corporates, activists, and students. All united by a commitment to building a future that respects the planet.
Afterwards, guests are invited to connect over drinks and informal networking in this inspiring setting. The perfect way to kick off two days of dialogue, pitches, and partnership-building in Paris.
More than just a map
This isn’t just a nice idea on a map. It’s already one of the world’s most powerful climate tech ecosystems.
What you’re looking at is a collection of some of the world’s most prolific climate tech clusters. What’s special is that they’re all reachable within four hours by train from London.
Within this region, you’ll find a critical mass of world-leading universities, ambitious climate investors, deep tech hubs, and some of Europe’s most forward-thinking cities: Cambridge, Paris, Cologne, Amsterdam, Antwerp, London, Eindhoven, Charleroi, Oxford. The list goes on.
We don’t believe the world needs another isolated innovation district or local hub. What it does need is a joined-up ecosystem that moves at the speed of the climate crisis.
An ecosystem where founders, researchers, investors, corporates, and governments collaborate across borders to scale solutions that work.
This is the ecosystem we’re building. We call it the Climate Tech SuperCluster.
